DSM501A Dust Particles Sensor

Description

What it is

The DSM501A is a particle dust air sensor for measuring dust particles in the air, ideal for DIY projects and environmental monitoring. With the DSM501A, you can detect fine dust concentrations such as PM10 and PM2.5.

Features

• Precise air particle dust sensor
• Ideally suited for monitoring PM10 and PM2.5
• Compatible with Arduino and ESP projects

What it is for

The DSM501A is used to create air monitoring systems that display data on an OLED screen. It is suitable for both beginners and more experienced makers.

Tutorial: How to use DSM501A Dust Particles

The DSM501A is a fine dust and atmospheric particulate sensor ideal for DIY projects such as air monitors. It is suitable for both beginners and more experienced makers.

What you need

• Arduino Uno
• USB A-Micro B cable
• 3D Printer (for home)
• 5V power supply

Steps

1. Connect the DSM501A to the Arduino pin VCC and GND for power.
2. Connect the following pins of the DSM501A to the digital pins of the Arduino: SDA to A4, SCL to A5.
3. Install the Adafruit_ParticleSensor.h library in the Arduino IDE library manager.
4. Include ‘Adafruit_ParticleSensor.h’ in the sketch and instantiate the sensor object.
5. Configure the I2C bus with beginWire() in the setup() function.
6. Call readPM10andPM25() to read the PM10 and PM2.5 dust data.
7. Display the read values on the serial monitor or on a connected OLED display.
8. Check the sensor specifications in the datasheet for further configurations.

Example code

// Includere la libreria
#include <Adafruit_ParticleSensor.h>
// Istanziare l'oggetto
Adafruit_ParticleSensor particlesensor = Adafruit_ParticleSensor();
void setup() {
  Serial.begin(9600);
  if (!particlesensor.begin()) {
    while (1); // Bloccare il codice se non riesce a inizializzare.
  }
}
void loop() {
  particlesensor.readPM10andPM25();
  Serial.print("PM1.0: "); Serial.println(particlesensor.PM1_0);
}

Mini project
